GlRDER-RAIL AND PROCESS OF MANUFACTURING THE SAME.

SPECIFICATION forming part of Letters Patent No. 486,211, dated November15, 1892.

Application filed February 23, 1892. Serial No- 422,364=. (No model.)

To all whom it may concern.-

Be it known that I, RUDOLPH M. HUNTER, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented an Improvement inGirder-Rails and the Process of Manufacturing the Same, of which thefollowing is a specification.

My invention has reference to girder-rails and the process ofmanufacturing the same; and it consists of certain improvements, whichare fully set forth in the following specification, and shown in theaccompanying drawings, which form a part hereof. This application (GaseNo. 215) has special reference to rails adapted to street-railwaypurposes, and has for its object the construction of a rail and foot inone integral piece to obviate the necessity of independent chairs.

Heretofore it has been customary to roll a girder-rail with the head andtram portions at the upper part of the web and foot-flanges at the basethereof and to support the said girder-rail upon cast or wrought ironchairs,

which are spiked to'cross-ties arranged at a level below the paving. Theuse of chairs is a necessity for the purpose of bridging the spacebetween the foot of the rail and the cross-ties, which necessarily arelocated at a depth below the bottom of the ordinary Belgian blocks orpaving-stones.

The object of my invention is to reduce the expense in the manufactureof girder-rails of great depth in the web or the distance between thebase-flanges and the head, and at the same time to form the entire railof one integral structure.

In carrying out my invention I roll a rail with a deep web and the usualhead and tram, and then as a subsequent operation cut the lower edge ofthe web, so as to form strips of metal parallel with the length of therail, which strips are then bent at an angle to the length of the railand formed into foot-flanges at a lower depth than the original loweredge of the said web, thereby giving to the rail the great depthrequired without the necessity of using independent chairs. In practiceone of the foot-pieces will preferably project to one side of the weband the next foot-piece to the opposite side, and so on, whereby greatstability is given to the rail as an entirety. It

is immaterial to my invention how these portions which form the footparts of the rail are bent to extend below the original depth of theweb; but I show the preferred methods of bending said foot portions.

Referring to the drawtngs, Figure l is a side elevation of a girder-railembodying my invention. Fig. 2 is a cross-section of a portion of arailway, showing my improved rail in its relation with the paving-stonesand cross-tie. Fig. 3 is a perspective View of one end of my improvedrail shown in Fig.1. Fig. 4 is a side elevation of a modification of myimproved rail, and Fig. 5 is a perspective view illustrating a modifiedmanner of bending the foot portions.

A is the rail proper, and is provided with the head B and the side tramG, which may be of the usual construction.

D is the vertical web, and as originally rolled is of the depthindicated by the dotted line in the several figures. At given distancesalong the lower edge of this web D pieces E are cut so as to formlongitudinal strips, which may then by any suitable machine or by handbe bent downward at an angle to the length of the rail to form theintegral portions E, the lower parts of which are bent to a horizontalposition to form the feet e, which may be perforated to receive thespikes. These perforations may be made at the same time that the stripsE are cut. The preferred method of bending the foot portions E is shownin Figs. 1, 2, and 3, in which the strip E is first bent backward andupward on the diagonal bend I and then bentoutward and downward on thehorizontal bend 2'. The foot E is preferably extended out at a slightangle away from the web as it approaches the cross-tie F. It will thusbe seen that the web D is provided with a series of downwardlyprojectingportions H, to which the foot portions E are directly or integrallyattached.

This structure, it will be seen, will give great strength coupled with agiven amount of elasticity, and will permit the greatest depth betweenthe head and the foot required, combined with the least depth in the WebD permitted. The full height of the rail is only limited by the lengthof the portions E, and this may be increased or decreased, as desired.

In the construction shown in Fig. 4 I have slmply shown the footportions E arranged in pairs, one of which projects in one directionfrom the web and the other of which projects in the opposite direction.In this case the portions E on one side of the rail are bent in theopposite directions from those of the portlons E on the opposite side ofthe rail. 0therwise the construction is the same as that shown in Figs.1, 2, and 3. In place of bendmg the portions E first upon the diagonal Iand then upon the horizontal 1' they may be bent first upon a verticallinet'and then upon a diagonal line I, as indicated in Fig. 5. It isimmaterial to my invention how the foot portlons E are formed upon theweb D so long as they are integral with it and are connected thereto bybent portions. Therefore I do notlimit myself to the details hereinshown.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A girder-rail formed of a longitudinal web and head portion and aseries of foot portions formed integral with the web and connectedthereto by bends.

2. Agirder-rail formed ofalongitudinal web and head portion and aseriesof foot portions formed integral with the web and connected thereto bybends and in which some of said foot portions project to one side of theweb and some to the other side of the web.

3. In a girder-rail, the combination of the head, web, and foot portionsformed integral and in which the web is provided with a se ries ofdownwardly-projecting portions connecting integrally with the footportions by means of bent portions of the metal.

4. In a girder-rail, the combination of the head, web, and foot portionsformed of oneintegral piece of metal and in which the foot portionsextend below the web and are connected at the extreme lower portionthereof by bent portions interposed between the said web and foot and inwhich the depth of the finished rail is greater than the extreme depthof the web prior to the formation of the foot portions thereon.

5. In a girder-rail, the combination of the web 1), formed with the headB and tram C at the top and integrally connected with the foot portionsE by means of the bent portions I and t.

6. The herein-described method of forming a girder-rail of great depthbetween the foot and the head, which consists of first rolling agirder-rail with head and tram and web, but without foot portions, thencutting, 0r notching the lower edge of the web to form longitudinalstrips, and subsequently bending the said strips at an angle to thelength of the rail and downward or away from the head portion thereof toform feet.

In testimony of which invention I have hereunto set my hand.
